Nicotine and other chemicals in e-liquids may induce microangiopathy, leading to vasoconstriction and reduced renal perfusion, thus contributing to AKI. Chronic exposure to nicotine also promotes an inflammatory response, increasing the risk of interstitial nephritis. Additionally, glomerular damage due to continuous use of vapers has been linked to albuminuria and progression of focal segmental glomerulosclerosis (FSGS), a condition that can lead to CKD.

The treatments for each class of lupus nephritis are described, as well as the therapeutic targets, underlining similarities and differences between the guidelines. In general, they recommend that induction (\"initial\") treatment of proliferative classes be performed with monotherapy using mycophenolate or intravenous cyclophosphamide, or with multitarget regimens, using corticosteroids, mycophenolate or cyclophosphamide, and a calcineurin inhibitor or belimumab as a third drug. A change in therapy should be considered if the expected response target is not achieved, which presents subtle differences among current consensus guidelines. Maintenance (\"subsequent\") treatment should preferably be performed with mycophenolate, azathioprine, or multi-target therapies. Emerging scientific evidence has provided treatment options that impact the management of lupus nephritis, thereby justifying the publication of new guidelines in recent months. Critically analyzing these guidelines may assist in decision-making for the individualized treatment of individuals with this disease.</p>","PeriodicalId":14724,"journal":{"name":"Jornal brasileiro de nefrologia : 'orgao oficial de Sociedades Brasileira e Latino-Americana de Nefrologia","volume":"47 4","pages":"e20250092"},"PeriodicalIF":1.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12520630/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145286281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
